Brief Summary:
Ambroxol is a simple cough medicine that is predicted to slow ALS disease progression. This study aims to investigate if ambroxol in high doses is effective in treating ALS. This study will be carried out across 5 research sites in Australia (2 NSW, 1 VIC, 1 SA and 1 TAS), where newly diagnosed ALS patients will be asked to participate. Participation will be over a 32-week period, where they will come in for a 4-week screening, 24-week treatment, and 4-week end of study safety follow-up period. The participants will receive either the placebo or drug solution that they will take three times a day, up-dosing each week until they reach the maximum dose or highest dose they can tolerate. Throughout the study their disease progression will be assessed using tests, questionnaires, and blood biomarkers.
Detailed Description:
This study is a double-blind, randomised, placebo-controlled phase 2 clinical trial, to assess the safety, tolerability and efficacy of ambroxol therapy in ALS patients by using electrophysiological and functional measures to detect preservation of motor units. The study design will have participants be randomised to either ambroxol or placebo at a 2:1 ratio (ambroxol (n=34) and placebo (n=16)). Participants randomised to the active arm will receive various doses of ambroxol in solution, taken orally, three times a day. Doses will be increased pending a safety review for each participant. The doses will be 180mg per day, 260mg per day, 540mg per day, 900mg per day, and 1260 mg per day. Each week safety bloods will be performed to assess tolerance to the dose. Participants randomised to the control arm will receive a placebo for the duration of the study. Disease progression will be assessed by the following, time to event (death, need for tracheostomy, the need for gastrostomy feeding or non-invasive ventilation support (≥12 hours a day in a 24-hour period), or ≥6-point progression (ALS functional rating score-revised).
